SEBACEOUS, prostate, and mucous glands.Endocrine glands: The glands which secrete hormones and other substances directly into the bloodstream are called endocrine glands. Eg. Pituitary, Pineal, Thyroid, Thymus, Gonads, etc.Explanation:The posterior part of the pituitary gland also called Neurohypophysis (pars nervosa) releases oxytocin.Oxytocin is synthesized by the hypothalamus and is transported axonally to the neurohypophysis.Oxytocin acts on the smooth muscles of our body and STIMULATES their contraction. In females, it stimulates a vigorous contraction of the uterus at the time of childbirth, and milk ejection from the mammary gland. For this reason, it is also called the birth hormone. The pars distalis region of the pituitary, commonly called anterior pituitary, produces growth hormone (GH), prolactin (PRL), thyroid-stimulating hormone (TSH), adrenocorticotrophic hormone (ACTH), luteinizing hormone (LH), and follicle-stimulating hormone (FSH).Pineal gland: It is present on the dorsal side of the forebrain. It produces an enzyme called melatonin which is responsible for maintaining the diurnal rhythm (24-hour) of the body like the sleep-wake cycle, body temperature, etc.In addition, melatonin also influences metabolism, pigmentation, the menstrual cycle as well as our DEFENSE capability.The thyroid gland is composed of two lobes which are present on either side of the TRACHEA. Both the lobes are interconnected with a THIN flap of connective tissue called the isthmus. It produces the enzyme thyroxine required for iodine metabolism.
